CIGAR LIGHTER.

Application filed September To all whom it may concern:

Be it known that 1, CHARLES CUNo, a citizen of the United States of America, r esiding at Meriden, Connecticut, have invented a new and useful Cigar Lighter, of which the following is a specification. I

y invention relates to an electric. heating element, which is particularly adapted for use as a cigar lighter."

In most instances, in small cigar lighters as heretofore made, it has been impossible to provide a sufiicient length of resistance wire in the limited space provided to adapt the device to the heavier voltages, and it has therefore been the practice to inse t a rheostat or other resistance in the circuit at a point remote from the device itself.

It is an object of my invention to provide a cigar lighter tip which is so constructed that one sized tip may be adapted to either the lower or the relatively higher voltages, and in which all of the resistance necessary is embodied in the tip itself.

A further object is to simplify and improve the construction and serviceability of small heating devices of this character.

In the drawings 1 have shown, for illustrative purposes only, a. preferred form 05 my invention, in which Figure l is a relatively enlarged view or" a cigar lighter tip embodying features of my invention;

Fig. 2 is a view in side elevation of the form shown in Fig. 1, one quarter being cut away to illustrate the section;

Fig. 3 is a still further enlarged view of parts shown in Figs. 1 and 2, the same being shown as separated;

Fig. l is a side elevation, on a relatively reduced scale, of a slightly modified form of the complete article,

in said drawings, 5 indicatesa body member of insulating material. such as porcelain or lava. This piece is generally cylindrical in form. Thefront end of the body is recessed, as indicated at 6, (Fig. 3), and the edge of the recess is preferably undercut to form an inwardly projecting flange or lip 7. The body 5 has a surrounding groove 8 in its side, for receiving a part of the resistance element of the device. Suitable wire passages may be provided. In the form shown a central passage 9 extends longitudinally through the body 5, while in the outside or" saidbody there is a longitudinally 13, 1922. Serial 1T0. 587,905.

disposed slot lO. The rear end of the body has a projecting boss 11 passage 9 extends.

12 indicates a metal ferrule for er losing at least a part of the base. This ferrule has an end aperture 13 through which the boss 11 extends. The upper edge of the ferrule in the completed device may be beaded over into the groove 8, as indicated at It, to hold the ferrule in place.

A heating element in the form of a fiat coil of resistance wire 15 is positioned within the end recess 6, and the outside convolution of said coil preferably extends into the tin dercut portion and beneath the lip or flange 7, so as to assist in holding the coil in place. The inner end or" the heater coil extends through the central passage 9 and, in the form shown, is embedded in a center soit metal terminal 16 at the end of the boss 11. The opposite end of the heating coil extends downwardly through theportion of the slot 10- above the groove 8 and, when more resistan e is desired than is furnished by the heater coil, it may be wound one or more times around the body in the groove 8. This end of the resistance wire is electrically connected to the ferrule 12 and, in the form shown, this end extends through a part of the slot 10 to the base of the ferrule, where through which the it is embedded in the soft metal or solder 1'1",

The modified torn-1 shown in Fig. is substantially the same as the form heretofore described, except that the end of the ferrule extends upwardly, so as to substany cover the groove 8, and an intermeportion of the ferrule may be swaged or. beaded in, indicated at 18, so as'to hold e ferrule on the body.

tip or plug may be thrust into any The suitable well known receiving socket, and the usual means, such as the pins 19, may be provided for locking the plug in place. The receiving socket for the plug shown would, of course, have'the usual contacts for malring electrical connection with the resistance coil, as is common in such sockets.

With an arrangement or" parts such as described it is possible to make the tip or lug of small size, and by varying the cunt of resistance wound around the side of the: body, a tip designed for any desired voltage may be produced. Cigar lighters are used quite extensivelyon automobiles,

where the batteries commonly supply curnish the needed length of resistancerwire' admirably adapted.

some instances for round wire.- m.

rent at six or twelve volts, and for. such voltages my present formgof cigar lighter is It is apparent, however, that the adaptability of the device is not limited to any specific range of voltage.

In the preferred form the surrounding gro'ove 8,which is designed to receive what Imay term the resistance coil, is preferably of annular form and wide enough to take the desired number of turns of wire to furcoil in a broadly descriptive sense t0"inelude a grid or other forms of heat ngzor resistance element.
